Thanks for helping. I recently purchased a Bally Continental 847-5, 6-coin dime machine. So far, everything works just fine except it does not return the 7th (or more) coins to the coin tray like it is suppose to. It just keeps the coins and the 6th coin light keeps on clicking like it received the 6th coin. I think that someone in its past fooled with it as I read that it hums when it operates properly, which is fine with me. I would like it to work as intended and reject the extra coins to the coin tray. Can anyone help me on this one? I am a novice, but do know a little about these (how to use a volt/ohm meter and I am a good cleaner--Ha!). Thanks, Vito
